This is generated by class wizard and the purpose is to have one unique identifier string (probably using date and time info and things like that). So that's why it looks so complicated. But you could simply replace that string with one of yours (anything you want, but it must be unique in your complete project).

Dear all,
I am developing one application containing propertysheet. I want to validate the data that user enters in property pages.
The problem I am facing is, when user enters wrong data, I validate this data in property page "OnOK" handler and corresponding message is shown to user. But when user clicks OK button on message box, message box as well as propertysheet get closed. I want this propertysheet remain open so that user can correct the wrong data entered.
How to do this?
Thanks in advance.

Maybe you should do the validation in OnKillActive handler of property page. According to documentation, "override this member function to perform special data validation tasks". You have to display your error box here and then return FALSE if data are invalid.

thank you very much its working

If the validation fails, exit the OnOK and do NOT call the OnOK function in the Paerent class. There are better solutions for validation. Each time a field is updated, you should check wheter the information is valid. As long as not all information is valid, you can disable the OK button. Think of handlers like EN_CHANGE (EDIT field) or SELCHANGE (Listbox) etc. I normally add to each dialog a member function to do all validations. It is called each time the user changes anything.

What i am trying to do is make a console program that gets playlist info from winamp and stores 2 things, the track number and the corresponding track name and stores it into a vector that is a struct with and int and a char defined like this:
struct sIPlaylist
{
char *Name;
int Position;
};
vector <siplaylist> dPlaylist;
The problem that i am having is that after i do a loop and go through the entire playlist and store both values for each song when i try to recall it like this:
Console::WriteLine(dPlaylist.at(a).Name);
no matter what number i put at a the text is always the last song name in the playlist escentially all of the Name part of the vector are the same text. this is how the loop is defined:
void CWinamp::gEntirePlaylist()
{
sIPlaylist tmp; // i think this might be where my problem is but im reseting the values at the beginning of each loop
for(int i=0; i < wInfo.pTotal ; i++) // run the loop until the end of the playlist
{
tmp.Name="";
tmp.Position=i+1;
tmp.Name=gTrackName(i); // gTrackName returns a char * with the song name of playlist track number i
dPlaylist.push_back(tmp); // move the lastest info to the bottom of the vector
}
Console::WriteLine(dPlaylist.size());
Console::Write(dPlaylist.at(222).Position); // this works perfectly
Console::Write(". ");
Console::WriteLine(dPlaylist.at(222).Name);
}
This is the console output:
222. Benny Bennassi .... Whos your daddy
that song isnt actually number 222 but actually number 3111 which is the last song in the playlist.
Im not sure what im missing but i obviously have some part of my code wrong and i would really appreciate any help.

The problem is probably because you don't use the char* correctly. The problem is probably in the function gTrackName but it is difficult to see wihtout seing the code. You cannot simply copy a string into your char array just by using =.
It would be much more efficient if you use the string from the STL also:
struct sIPlaylist
{
std::string Name;
int Position;
};

I suppose "char * Name" field of all of your sIPlaylist objects keeps a pointer to a string which is build by gTrackName function. This string is overwritten by each execution of gTrackName function, that’s why you only see the last value.
A solution is to keep the name inside the sIPlaylist structure. You can first define it as
struct sIPlaylist
{
char Name[100];
int Position;
};and then use string-copy function:
strcpy(tmp.Name, gTrackName(i));
In more elaborated program, you should use dynamic allocation, or better get the assistance of std::string class from STL. In MFC projects, you can use CString class.
I hope it helps.

i put the popup menu when we right click the listbox item.
by doing this follwing things.
1.i create a new class CMyList derived from CListBox
2. in that class i overwrite the COntext menu()
by following code
HMENU hmenu,hmenuPopup;
hmenu = LoadMenu(AfxGetApp()->m_hInstance,(LPCTSTR) IDR_MENU4);
hmenuPopup = GetSubMenu(hmenu, 0);
TrackPopupMenu(hmenuPopup, TPM_LEFTALIGN | TPM_LEFTBUTTON|TPM_RIGHTBUTTON,point.x,point.y, 0,m_hWnd, NULL);
.
now how can i handle this events.
|
|
|
|
|
if you write this code now what do you need i think you declare contextmenu

I think you can add the TPM_RETURNCMD flag to the second parameter of TrackPopupMenu function. In this case the function will return the ID of the clicked menu item, or zero otherwise. Then do the action according to received ID.

hi,
I have one clarification, I just want to know how to call stored
procedures in CDaoDatabase.
After the submit button I need to call one stored procedure by name
STORE_PROCEDURE1 with input parameters as
name,no,mark1,mark2
By using ADO I think we can use like this below. I just want to know how
to use in DAO.
With AdoComm
.CommandText = "{call PROEX.KPP_LFE.PPP_INSTPP_EMBARQUE_AUX(?)}"
.CommandType = adCmdStoredProc
Set AdoParamRet = .CreateParameter("Retorno", adBSTR, adParamInputOutput,
, vfRsEmb)
Call .Parameters.Append(AdoParamRet)
.Properties("PLSQLRSet") = True
Set vfRsEmbRet = .Execute
i want to do the same thing in DAO using CDaoDatabse
Try again and again,
At last you will say
I don't know the meaning for impossible.,.

When you send a "New Message" we can see it and you don't need to send a new thread
